Bisphosphonates are nonmetabolizable analogs of pyrophosphates. They have a high selectivity to bone remodeling sites, become retained and recycled, providing a long duration of continual effect after discontinuation. Bisphosphonates have been registered for postmenopausal osteoporosis for 20 years. Four bisphosphonates are currently registered for postmenopausal osteoporosis – alendronate, ris...

In the past 2 years, an increasing number of reports have appeared in the medical literature that suggest that the use of bisphosphonates, especially intravenous bisphosphonates, is associated with osteonecrosis of the jaw (ONJ). The majority of these reports are in patients with multiple myeloma, breast cancer, or other malignancies. In connection with these malignancies, the patients were rec...

Bisphosphonates are a class of drugs that are widely used to inhibit loss of bone mass in patients. We show here that the administration of clinically relevant doses of bisphosphonates in mice increases antibody responses to live and inactive viruses, proteins, haptens, and existing commercial vaccine formulations. Bisphosphonates exert this adjuvant-like activity in the absence of CD4(+) and γ...

Bisphosphonates have an established role in treating tumor-induced hypercalcemia and decreasing the incidence of skeletal-related events. Recent data suggest that these agents may also prevent skeletal metastases. This review explains how cancer metastasizes to bone and how bisphosphonates may block this process, with a summary of clinical trials supporting the use of bisphosphonates to treat a...

This review is made to establish the convenience of dental implant treatment in patients receiving bisphosphonates or programmed to receive such drugs, with a description of their mechanisms of action and the way in which they can affect the mandibular or maxillary bone of dental implant candidates. In turn, a description is provided of the key elements for evaluating the benefit-risk ratio in ...

PURPOSE Bisphosphonates (such as risedronate and zoledronate) are widely used inhibitors of bone resorption. Despite their in vitro antiproliferative effects in various cancer cells, bisphosphonates have not exhibited significant antitumor efficacy in animal models of visceral cancer, which may be due to their poor bioavailability. The diagnostic use of radioactive bisphosphonates has revealed ...

Apart from the well-known mechanism of bisphosphonates' cellular effect, embryonic development and the specific features of alveolar bone homeostasis have been discussed. The unique ethiopathogenic mechanism which relates osteonecrosis of the jaw and bisphosphonates treatment has not been explained. The emphasis lies on the toxicological effects of bisphosphonates on the physiology of the alveo...

BACKGROUND Bone is the most common site of breast cancer metastases. Skeletal metastases may be associated with harmful and painful events such as fractures, spinal cord compression, and hypercalcemia. By inhibiting osteoclasts and bone resorption, bisphosphonates can interrupt the process of bone destruction and decrease the risk of skeletal complications. METHODS A review of the literature ...

Osteonecrosis of the jaw has been described in patients taking bisphosphonates after oral surgery procedures, including the placement of dental implants. This review is an update of the relationship between bisphosphonates and dental implants. Results obtained by different authors are compared, contrasting earlier studies where an improvement in implant osseointegration using bisphosphonates wa...

Bisphosphonates are synthetic compounds similar to organic pyrophosphates. The bioavailability of intravenous preparations is 100%, whereas the availability of oral therapy ranges from 1 to 5%. About 50% to 80% of free bisphosphonates are incorporated into bone. Because of their urinary elimination, bisphosphonates must be carefully administered in chronic kidney disease (CKD) patients. In spit...
